Wylfa Newydd – About Our Site

The Wylfa Newydd site, on the Isle of Anglesey, is ideally situated for low carbon nuclear power production.

Our proposals for Wylfa Newydd will bring significant investment and benefits to the region. With billions of pounds of new infrastructure, Horizon Nuclear Power is committed to the long-term future of the area.

The site is on land beside the former Magnox Wylfa Power Station, which is now being decommissioned. It provides good foundation conditions for a new nuclear power station and is high above sea level, which simplifies the process of managing flood risks.

We aim to secure first electricity generation at Wylfa Newydd in the mid 2020s.

Developing Wylfa Newydd will be a large construction project. The different components of our proposals are likely to include:

a power station, including two nuclear reactors with a minimum generating capacity of 2900 MW;

a Marine Off-Loading Facility (MOLF);

cooling water intake and outfall structure

electricity transmission infrastructure;

other associated buildings, such as administration offices, park and ride facilities, temporary worker accommodation, and at least one logistics centre;

construction of a temporary Site Campus to accommodate construction workers;

interim waste and spent-fuel storage facilities;

access roads; and

measures and initiatives to manage any impacts during the construction and operation of a new power station.

Major project milestonesThere are several key stages in the planning process before any construction can take place. To build a new nuclear power station a Development Consent Order (DCO) application must be submitted to The Planning Inspectorate. This process involves a significant period of consultation and can take several years to complete.
